Can't monitor sound playing on my computer

Hi, new to the forum but have been using Audacity for years. Now on new MBP running High Sierra and 2.2.0. Can’t seem to record and hear the sound simultaneously. Audacity recording/playback settings are as I’ve always had them - Core Audio/Soundflower (2ch)/2 (Stereo) Recording Channels/Built-in Output. In system prefs, input is set to Soundflower (2ch). When output is set to multi-output device or internal speakers, I can hear the sound, but nothing records. When output is set to Soundflower (2ch), the recording meter toolbar activates, and sound is recorded, but I can no longer monitor the sound live. Help! What am I doing wrong all of a sudden?

Do you have this Audacity setting?
